概述

Description

BLM41PG471SN1L is a Murata ferrite-bead EMI filter (SMD) in the BLM41 series. It is used in series with a supply or signal line to suppress high-frequency noise and improve EMC.
Key points:
- Impedance code 471 corresponds to about 470 Ω at 100 MHz, making it effective for EMI suppression on power and data lines.
- Pb-free/ RoHS-compliant (the “PG” suffix indicates lead-free).
- Surface-mount device designed for standard reflow soldering; part variant “SN1L” relates to terminations/packaging options.
Typical uses:
- Filtering noise on DC power rails and signal lines in consumer electronics, computers, networking gear, and RF/ communications circuits.
Note:
- For exact dimensions, DC resistance, current rating, temperature range, and packaging, consult the Murata BLM41PG471SN1L datasheet. If you want, I can summarize the full specs from the datasheet.

Features

BLM41PG471SN1L features (concise):
- Ferrite bead EMI filter for a single line, used to suppress high-frequency noise.
- Impedance: 470 Ω (typ) at 100 MHz (helps attenuate HF).
- Very low DC resistance to minimize voltage drop and heat.
- Surface-mount package (compact 4.x mm footprint; suitable for dense layouts).
- Wide operating temperature range (-55°C to +125°C typical).
- RoHS compliant, Pb-free; suitable for consumer, mobile, and automotive/industrial use.

Package

BLM41PG471SN1L is a BLM41 series SMD ferrite bead in a 4.1 × 3.2 mm package (two-terminal, surface-mount).

Pinout

8 pins. It is a ferrite-bead EMI filter array (4-channel). Each channel provides a ferrite bead for high-frequency noise suppression on lines; impedance ≈470 Ω at 100 MHz per bead.

Manufacturer

- Manufacturer: Murata Manufacturing Co., Ltd. (Murata)
- What kind of company: A Japanese multinational electronics components maker that designs and manufactures passive components (ferrite beads, capacitors, inductors, sensors) and related electronic devices.

Application

BLM41PG471SN1L is a ferrite-bead EMI suppressor. Common applications:
- Inline noise suppression on power rails and data lines
- Consumer electronics (mobile devices, laptops, TVs)
- Automotive and industrial electronics for EMC compliance
- Networking/telecom equipment, servers, switches
- Filtering on switching regulator outputs and near connectors (USB, HDMI, PCIe)
- Used to help meet EMI/EMC standards by attenuating high-frequency noise

Equivalent

Would you like 1:1 cross references from other brands (TDK, Würth, Coilcraft, etc.) for the same spec: ferrite bead, 1206 package, ~470 Ω impedance at 100 MHz? If yes, I’ll fetch exact part numbers. Also confirm if 0.1" (1206) footprint and tolerance are acceptable.
